Hey, at least they are bringing out HV controllers. The boat guys are crazy, if you look around you will see that they are running the huge lehner and neu motors on ridiculous voltages in tiny boats! A guy did 140 in a park pond with an outrigger for petes sake. I have played with the non-HV hydra and it is a nice controller, can handle 6s and the water cooling does help the heat issues. My 45 mph supervee running lipo and the stock esc/motor does not even get warm. I think that the car controllers are the most difficult to get right due to the massive current spikes and partial throttle running. Air cooling tends to be much less efficent than water cooling. Imagine how cool a car esc would run with a constant flow of 60f air over it. Larger capps seem to help with the heat issue due to partial load, but even they heat up eventually. And we have to remember that not everyone is crazy enought to buy 10s worth of lipos to test out a theory!
